Images as soon as I actually bother to pick up a pencil ...
Garrhadam, or "Grundgy," as he's become known around the Diver's Club (although not to his face), is a Tharkoldu mage who had the great misfortune to have part of his brain blown out through the back of his head and across several square feet of asphalt. This, as one can imagine, had a profoundly negative effect on his personality ... there's a reason we call him "Grundgy."
(Update: thanks to some creative nanotech and a really convoluted plot-line, Grundgy has pulled himself together and will now mercilessly pummel anyone who calls him by that hated nickname.)
Gru ... er, Garrhadam is actually Diesel's chief bartender. Makes a wicked Bloody Mary, too. One of the best Tharkoldu mages you'll find outside of the cosm. Quirky as all get-out, and, when the mood takes him, a terrible flirt.
I don't have Garrhadam's stats yet, but I'll post them ASAP.
